I love customizing my IDE. Especially when it comes to the visual appearance. I spend hours finding the right theme, customizing the keymaps, adjusting and arranging the windows so that everything looks exactly the way I want it to. The IDE is something very personal. Or at least it is for me and many others. There are also psychopaths who install the IDE and just leave everything as it is. Yes, exactly with the default color theme! That's really beyond my comprehension. But anyway, this is about something else. It's not about the IDE but about the person in front of it and what you do with it. Thinking of Neovim? You guessed right. I worked with it myself for a few months. And still do regularly but for all that is holy, it's not the only true IDE for “real” developers. VsCode is not the …  ( 4 min )

Why I introduced This DevOps Definition 🎯 The Realization Behind the Definition What This Definition Truly Embraces 🔮 Why This Definition Matters — Now and In the Future This definition matters in 2025 and beyond because: 📘 See the official GitHub repo: https://github.com/sresrinivas/etoe 📌 The Final Thought DevOps isn't a title. It's not a tool. It's a discipline that unites engineering depth in systems and applications — and this is the definition that will shape the future of DevOps engineering.  ( 4 min )

Users can track all the dares they have accepted and those they have declined, keeping their challenge history organized.

"Your CRUD app is a ticking time bomb. Here’s how to defuse it—without a rewrite." Legacy systems are like old houses: Every change risks breaking something No one remembers why the plumbing works this way Adding a new room feels impossible But migrating to event sourcing doesn’t require burning it all down. Here’s how we moved a 500-table Rails monolith to event sourcing—one component at a time—without downtime. Phase 1: Lay the Foundation Step 1: Identify the Pain Points Start with the highest-value, highest-pain areas: Audit-heavy domains (payments, user access) Complex workflows (order fulfillment) Frequent "how did this happen?" debugging Avoid: Static reference data (e.g., product catalogs).

In this blog post, we’ll explore how to automate AWS infrastructure provisioning using CloudFormation templates orchestrated by Jenkins pipelines. We'll build a web server environment deployed across three stages: development, staging, and production, following a CI/CD approach. This post builds upon the previous blog where we detailed setting up a Jenkins server on an EC2 instance and configuring it with essential plugins. We’ll now use that Jenkins server to drive infrastructure-as-code (IaC) workflows using AWS CloudFormation. The high-level architecture for this solution involves: A Jenkins server deployed on an EC2 instance in a public subnet. A Git repository containing the CloudFormation templates for creating network and compute resources. An S3 bucket to store the templates for ne…  ( 8 min )

For 16 years, I worked as an independent contractor for the company that marketed and sold websites under the BankSITE® brand. In 2022, I began building a new proprietary WordPress-based software system that would eventually become the foundation of BankSITE® Builder Pro (BBPro). That framework now powers over 100 live financial institution websites across the United States. Behind the name and brand was a single developer: me. My name is Bojan Josifoski, and I am the sole creator and author of the BBPro Core Framework. From 2022 to 2025, I designed, built, and maintained this proprietary platform in its entirety—including: Software architecture Full-stack development Update and deployment systems Version control and optimization There was never: A written employment contract A copyright assignment A license agreement In 2025, I registered the BBPro Core Framework with the U.S. Copyright Office under Case #: 1-14944175091. This was not an act of hostility, but a necessary step to preserve authorship and protect the continuity of a platform relied upon by over 100 U.S. banks. BBPro was never open source. It was not work-for-hire. It remains privately held and unlicensed. The BBPro software platform is protected by copyright and was never assigned or licensed to BankSITE® Services or any third party. I am open to ethical and legal solutions that support long-term continuity and compliance for institutions using BBPro. But I will no longer remain silent or invisible.

Biometric Authentication: Enhancing Security with Endpoint Protection and One-Time Passwords Biometric authentication has emerged as a powerful method of securing digital systems in an age where cyber threats are increasingly sophisticated. By using unique biological characteristics such as fingerprints, facial recognition, iris patterns, or voiceprints, biometric systems offer a more secure and convenient alternative to traditional password-based authentication. As digital transformation accelerates across industries, integrating biometric authentication with endpoint security and one-time passwords (OTPs) has become a crucial strategy for comprehensive protection.

Let me be honest — I wasted a lot of time trying to learn data analytics on my own. I started with free YouTube playlists, then bounced between Coursera, Excel crash courses, and random blogs. Each platform had a piece of the puzzle, but none of them really helped me connect the dots or stay on track. I needed something beginner-friendly, job-focused, and structured. After going down multiple Reddit and Quora rabbit holes, I enrolled in the Coding Ninjas Data Analytics Job Bootcamp. I wasn’t expecting miracles, but it turned out to be one of the more practical, real-world programs I’ve come across. What I Was Looking For in a Course A practical skill set to land a data analyst job Real projects I could add to my resume Mentorship and placement help A schedule that worked alongside my full-time job After weeks of comparing options like Scaler, Simplilearn, and Great Learning, I felt like most were either too expensive or overloaded with fluff. That’s when Coding Ninjas caught my eye—specifically their data analytics job bootcamp. What My Experience Has Been Like So Far Beginner-Friendly but Not Oversimplified Tons of Practice + Capstone Projects Placement Support That Isn’t Just a Gimmick A Few Things That Could Be Better The earlier Excel and SQL modules felt a bit slow if you’ve used them before. You still have to hustle—this isn’t a shortcut to a ₹10LPA role overnight. Final Thoughts: Is This the Best Data Analytics Course in India? You’ll still need to stay consistent and put in the hours, but if you do, you’ll come out of it with a solid portfolio, interview prep, and real-world confidence. No regrets here—and finally, I feel like I’m not just “learning,” I’m actually moving toward a job.  ( 4 min )

When I started building GenAI solutions, I felt confident working with models, prompts, and architecture — but the data part always felt like a black box. I kept asking myself: Where do I even begin if I want to use my own data? Every time I looked into it, I found a pile of scattered advice, incomplete setups, or tools that didn’t quite fit together. It reminded me of moving into a new house and opening the garage — only to find it packed with boxes from ten different people. You know there’s valuable stuff in there, but it’s all mixed up, mislabeled, and overwhelming. This post is what I wish someone had handed me back then — a clear, hands-on walkthrough of how to turn that chaotic garage into a well-organized workshop.

Recently I had to test a scenario where the laravel application detects which region a request is coming from and based on that chooses the correct payment gateway (domestic/international) to effect the payment. This was tricky for the following reasons: We were testing on servers which were in a VPN enclosed environment. And the VPN gateway always shows a United States IP. All gateways available to us were US based only. Using a different VPN wasn't possible as its against company policy (and also unsafe). Now normally, when such systems are built, they are usually built on the basis of geolocation (invasive, think of your browser asking you to share your location) or on the basis of IP Ranges (non-invasive, you can find these on many websites that tell you that you are from such and such…  ( 3 min )

As soon as I got a Keychron K10 Pro, I started to wonder what to do with those extra 4 keys on the corner. First, of course, I needed some cooler keycaps than square/circle/triangle/cross.

Hey everyone! Who doesn’t love a good puzzle game to pass the time — whether you're in line, on the bus, or anywhere else? That’s exactly why I decided to create Elementar! I was inspired by classic logic games like Tohu wa-bohu and even the famous LinkedIn Tango, but I added some unique twists and exclusive modes to make the experience even more fun and engaging! The core challenge is simple: fill the grid with an equal number of Fire 🔥 and Water 💧 symbols in each row and column. But watch out — you can’t place 3 of the same symbol in a row, either horizontally or vertically. That’s the golden rule! And the best part? I built Elementar as a Progressive Web App (PWA), so you can install it directly on your phone and play offline anytime — or just open it in your browser! 📱💻 You’ll find the full rules and mode details on the game’s page. Try it out and let me know what you think! 👉 Play Elementar now: https://elementar.vercel.app Got ideas for new modes, improvements, or puzzles you'd love to see?

When you’re building a feature-rich application that relies on Redis, naming your keys might seem trivial at first. But as your system grows, poorly named keys can become a mess—leading to bugs, data collisions, and serious maintenance headaches. That’s why it's important to follow clear and consistent naming conventions in Redis. The goal is to make your data structures not just usable, but self-explanatory. You want anyone looking at the data to instantly understand what a key represents, what kind of data it holds, and how it's organized. Redis doesn’t enforce a structure in key names, but you can create one yourself using colons : as separators. Example: user:1001:settings user:1001:cart order:20230621:items This naming style is both readable and machine-friendly. It acts like a pseud…  ( 4 min )

When working with AWS CDK in environments where OpenID Connect (OIDC) is used for role assumption—especially in CI/CD pipelines—developers often encounter cryptic permission-related errors.

Ensuring a safe and user-friendly environment on your platform is more critical than ever, especially with the rise of user-generated content across social media, forums, and e-commerce sites. NSFW (Not Safe For Work) images—encompassing explicit adult content, nudity, or sexual activity—can alienate users, damage your brand reputation, and even lead to legal challenges. Fortunately, the Deep Detect API offers a robust solution to detect and filter such content seamlessly. In this post, we’ll dive into how you can integrate this powerful tool into your platform to enhance safety and compliance. Deep Detect is a state-of-the-art SaaS platform designed to provide advanced image analysis services tailored for content moderation, security, and compliance. One of its key offerings is the NSFW d…  ( 5 min )

Power BI is quite an interesting data tool and one of the concepts that I have enjoyed working on is relationships. This simply refers to the connection made between two tables. It is created by joining two separate tables using a selected column that has similar information on both tables. The table selected first is the fact table and the other table is the dimension table. There is a primary key in one table which is the unique identifier that maps on to the foreign key in the other table. There are four types of relationships: i)One to One Consider two tables; one with sales date and another with calendar dates. The sales date can only match with one date on the calendar table, this creates a connection between the two tables based on these columns. ii)One to Many When you have customer table with customer id and sales table with customer id, the customer ID can match the sales table multiple times. This is because one customer can have multiple sales creating a one-to-many relationship. iii)Many to One For example, table with Sales information and another table with Products information. The common column between them is the product ID column. In this case, there are multiple sales that are made of one product. Therefore, multiple values on the sales table match with one value on the product table. iv)Many to Many Another thing about relationships is the cross-filter direction. This refers to the direction in which a filter that is applied on tables that have a relationship affect those tables. Relationships in PowerBI have made it easy to understand, explore and join tables for easier visualization of data and I can't wait to learn more!  ( 3 min )

Hey Devs 👋 Over the past few months, I’ve been building my solo SaaS project and wanted to share some reflections — especially about the tech stack I chose. While most indie hackers lean on lightweight setups like Node.js or Python, I decided to take a less-traveled path: combining Next.js and Spring Boot. Here's why I went with this setup — and what I learned along the way. Even though my backend is built with Spring Boot, I still made full use of Next.js’s server actions and full-stack features. Rather than calling the Spring Boot API directly from the browser, I routed all API calls through Next.js server components. This approach gave me: ✅ Server-side execution only (no client-side leaks) ✅ Invisible API calls in the browser network tab ✅ No CORS headaches This helped me build a more…  ( 4 min )

Legacy Contracts, Stuck in Time Why Do We Need Smart Contracts 2.0? Perception — the ability to sense changes in environment or state Memory — the ability to store and apply interaction and state history Agency — the ability to act proactively toward a goal without being called Adaptation & Evolution — the ability to adjust strategy based on experience or feedback Today’s smart contracts cannot remember past interactions, cannot initiate actions on their own, and cannot adjust their behavior based on long-term signals—whether on-chain or off-chain. This gap calls for a new primitive: a transition from function-based contracts to agent-based contracts. This isn’t just an upgrade in architecture—it’s a fundamental paradigm shift. At SeaOS, we define Smart Contracts 2.0 as: On-chain agents th…  ( 5 min )

All it takes is 5 minutes, you won't even need most of the text that's on here. Custom Domain -> I bought my custom domain at godaddy.com but you can also use other services such as hostgator.com, domains.cloudflare.com, namecheap.com. However, I did later find out that Vercel's pricing was lowest for the domains I was interested in. Your website -> Have it parked in a repo on http://github.com/ Hosting -> I used Vercel as it's FREE.99! (see their hobby tier) Go to vercel.com & register if you don't have an account just yet. Add a new project: Import your project and follow instructions to "Deploy", and you'll see "Adding a domain" as one of the next steps. Here you have a choice of buying or adding a domain. Type in the name of the domain you bought. Vercel will generate something like below for you. It might be multiple entries. Unless you bought your domain on Vercel, go to your domain provider to access DNS records configurations. For godaddy it's in here: https://account.godaddy.com/products Scroll down to your domain, click "DNS" and plug the values that Vercel generated for you there. Then go back to Vercel and click "refresh" on those generated entries. Ta-da! 🎉 Your portfolio should now be up and running.  ( 3 min )

Hey Dev Community 👋 I recently launched The Mindloom — an AI-powered mental wellness platform designed to make emotional support more accessible, reflective, and human. This wasn’t just a product build for me — it was a deeply personal journey as a builder and a thinker. It started with a simple thought: therapy helps, but access is hard. Scheduling sessions, costs, and most importantly — the fear of being judged — can hold people back. What if an empathetic, always-available AI companion could help people check in with themselves, journal openly, and feel heard? That seed turned into The Mindloom. I chose Next.js 15 as the foundation, combined with Supabase for database and auth (via Clerk), Upstash for vector embeddings, and ElevenLabs for voice interactions. The AI backend uses OpenAI'…  ( 3 min )

Some routes in your application require authentication or other conditions to be met before users can access them. TanStack Router provides a powerful guard mechanism to handle these scenarios through the beforeLoad function, which allows you to intercept route navigation and enforce access control rules before any components are rendered. When you define a route with createFileRoute you have can specify a function in the beforeLoad property. This function will be called before the route is loaded, allowing you to perform checks and potentially redirect the user if they don't meet the required conditions. An example: import { redirect, createFileRoute } from '@tanstack/react-router'; import { isAuthenticated } from '../utils/auth'; export const Route = createFileRoute('/profile')({ comp…  ( 5 min )

Why You Should Start Using a Clipboard Manager Today You copy something important, copy something else... aaand it's gone. Ever lost a long message you spent 10 minutes writing? Had to keep switching between apps to re-copy five different values? Or filled a long form just for the browser to refresh and for you to lose all the work you've done? We've all been there. That’s where clipboard managers come in - saving your day (and your sanity). A clipboard manager is an app that, well... manages your clipboard. Every time you copy something (Ctrl+C / ⌘+C) - it's saved in a special place among the stars called "the clipboard". When you paste (Ctrl+V / ⌘+V) - the most recent item from the clipboard is pasted in the foremost app. By default - your clipboard only remembers the last item you co…  ( 5 min )

Computers can't perfectly represent most decimal numbers! YES! You read that right...even I was like,"Wait, what? That can't be right!" But then I remembered this crazy story about Airane 5 explosion because of a tiny decimal point error, which I saw on an IG reel. Hence why precision matters! We naturally work in decimal (base-10) while computers use binary (base-2) arithmetic, This simple difference creates complex problems. For example, the seemingly simple number 0.1 becomes an endless sequence in binary: 0.00011001100110011... and 0.1 + 0.7 ≠ 0.8 To solve this complex problem of having a precise value IEEE 754 was introduced.

Some topics don't require code. Just courage. In tech, we often talk about building bridges between systems, teams, and communities. But sometimes, the bridges that matter most are the ones we build quietly between people. What happens when you offer someone your trust, your time, your effort, and they simply let go? Not every betrayal is loud. Sometimes it's a message left on read, a tone that changes, a silence that grows until you realize you're the only one still standing on what you both started. This isn’t about blame. It’s about recognizing when something shifts and deciding what to do with what remains. If this speaks to something you’ve felt, I wrote a story that might resonate.

Some days I feel unstoppable—deep in the zone, code flowing, tabs organized, energy locked in. Other days… it’s 4 PM, I’ve bounced between Slack, VS Code, Notion, and six Stack Overflow threads—and I can’t tell you what I actually finished. Being a developer comes with freedom. But no one talks enough about the pressure that freedom brings. Time is weird in this work. I used to think being constantly active meant I was making progress. But now, I catch myself asking: “What actually moved forward today?” Some days, the only real win was deleting code that no longer served a purpose—and that’s okay. There’s something powerful about a solid 2-hour coding window—no notifications, no background noise, just solving. Those moments don’t happen by accident. And they don’t happen every day. But when they do, they remind me why I started coding in the first place. I’ve tried Pomodoros, strict schedules, even time blocking. Sometimes they work. Other times, I need flexibility more than structure. The trick—for me, at least—is knowing which version of me is showing up that day. And adjusting without guilt. Burnout doesn’t always come from shipping too much. Sometimes it comes from staring at the same problem too long, getting nowhere, and losing the joy of the work. That’s when I step away. I don’t “quit”—I just give myself space to come back stronger. Some weeks I feel aligned. Others, I feel scattered. But I’ve learned to check in with myself—not just my code. “Am I creating, or just reacting today?” “Am I learning, or just collecting tabs?” “Do I feel behind—or just tired?” That’s made all the difference. How do you manage your time without losing momentum? Have you found a rhythm that works for you—or are you still figuring it out like me? What makes you feel in control of your time as a dev? Drop your thoughts. Let’s talk about the messy, honest side of productivity—no hustle posts, no hacks, just real dev life.  ( 4 min )

Given a large body of text, we (or in this case the systems we build) try to summarise the important points into a concise paragraph. Historically, the ways in which summarisation systems are categorised are numerous, but they essentially fall into two broad types: Extractive summarisation essentially treats it as a classification problem, where each sentence is considered as a binary classification problem, where 0 implies the sentence is not included in the final summary and 1 otherwise.

Signals in Angular 20 fundamentally simplify reactive programming by offering a lightweight, synchronous, and intuitive way to manage state changes in the application. Here’s how they make my life as a developer easier: No More Manual Subscriptions Unlike RxJS Observables, which require to manually subscribe and unsubscribe to avoid memory leaks, signals automatically notify the templates and dependent code when their values change. This eliminates a common source of bugs and boilerplate code. Example: import { signal } from '@angular/core'; const count = signal(0); count.set(1); // Update value console.log(count()); // Read value: 1 I don’t need to manage subscriptions—Angular takes care of it for me.

The Unsung Hero: Mastering assert in Production Python Introduction In late 2022, a seemingly innocuous deployment to our core recommendation service triggered a cascade of 500 errors. The root cause? A subtle change in the upstream data pipeline introduced negative values into a field we’d implicitly assumed was always positive. Our existing validation logic, focused on schema and data types, missed this semantic constraint. The incident highlighted a critical gap in our defensive programming strategy.

This week was a classic GSoC rollercoaster—funny moments, frustrating bugs, and fulfilling breakthroughs! The week began by finishing up a few pending tasks from codebase modernization. One of those tasks was commenting on Coderabbit's suggestions. Now, here's the funny part—when I saw the suggestions reacting and replying by themselves, I thought Aboo (my mentor) was responding manually. Turns out, Coderabbit talks back.My reaction? Mild panic, major confusion, and then a chuckle. Anyway, it's surprisingly helpful. Definitely the kind of AI pair programmer you don’t mind having around. A BIG mistake I made and I’m writing it in caps so future-me never forgets is this: Always use unique keys when working with Flutter's localization (gen-l10n)! For example: error profile_view_error, ib_land…  ( 4 min )

We need something better than pip — and that's where uv comes in. It’s a fast Python package manager and task runner that replaces pip, venv, and even parts of poetry, without the extra overhead. Though previously I wrote Do not use 'pip freeze' and Best way to create requirements.txt. You can read them... uv You can find the installation instructions for uv here uv init: Instant Project Setup uv init This command creates a boilerplate pyproject.toml and sets up your .venv — no manual steps needed. It automatically detects your Python version and prepares a minimal project environment. Need a package like rich? uv add rich This adds it to your pyproject.toml, installs it, and updates your uv.lock. No need to touch requirements.txt. Example usage with rich: from rich import print print("[bold green]Hello from UV-powered project![/bold green]") Instead of manually activating .venv, use: uv run main.py This runs your app inside the managed environment automatically. Yes, you can still run with python main.py, but that means you'll have to activate .venv manually: source .venv/bin/activate First run uv venv and then install all packages from pyproject.toml uv sync There’s more you can do: uv pip, uv pip freeze, uv sync --update, and more. You can even change Python versions or set a specific version in .python-version — check it out in their docs.  ( 3 min )

No, AI didn't take my job. It enhanced it. When ChatGPT first came out, I was skeptical. Those early prompts really surprised me — the results were good, although I also noticed some hallucinations and answers disconnected from reality due to the training data cutoff. That frustrated me at first, but I quickly understood why, and it became a secondary issue. Then the paid version launched. At first, I hesitated — it felt expensive — but I decided to give it a shot. I quickly integrated it into my workflow and, to my surprise, saw a meaningful boost in productivity. I think many of us have gone through similar phases. Now, I can’t imagine canceling the subscription or removing this tool from my day-to-day. And I’m not just talking about ChatGPT — I mean AI in general. I entered a spiral — w…  ( 4 min )

Over the last couple of weeks, I have had to upgrade some function apps which were written about 6 years ago. These function apps were triggered by logic apps and in most cases, the original implementation invoked the function apps via http connectors. It got me thinking about using http connectors but incorporating swagger definitions. Incorporating swagger definitions provide a better UX for integrating with function app. To start off, the function app code has to be annotated with openApi attributes and for c# projects the nugget package must be added. The nugget package to use is Microsoft.Azure.Functions.Worker.Extensions.OpenApi":Version="1.5.1" In the scenario been discussed, a shipping notice will be created.

🧠 Solving LeetCode Until I Become Top 1% — Day 27 🔹 Problem: 2138 Divide a String Into Groups of Size k Difficulty: #Easy Tags: #String, #Greedy Given a string s, divide it into groups of size k. If the final group is smaller than k, fill it with the given fill character until it reaches length k. Return a list of strings, each representing a group of size k. Brute Force Idea: Start taking substrings of length k in a loop and append them to a result list. If the final group is smaller than k, pad it manually. Optimized Strategy: First, check if s is divisible by k. If not, append the appropriate number of fill characters to make its length divisible by k. Then, iterate over the updated string with a step of size k and slice out chunks. class Solution: def divideString(self, s: str, k: int, fill: str) -> List[str]: res = [] n = len(s) s = s + (fill*(k-n%k) if n%k else '') start = 0 while start < len(s): res.append(s[start:start+k]) start += k return res Time: O(N) Traverses the string once to pad (if needed), and once to slice. Space: O(N) Output list stores all the k-sized chunks. ✅ Learned how to chunk a string cleanly using modulo logic and list comprehensions. 💡 Edge cases like "what if the string isn't divisible by k?" must be handled before chunking. 💭 This pattern is helpful for problems involving grouping, formatting, or padding strings to meet constraints.

No, la IA no me quitó el trabajo. Me lo potenció. Cuando salió ChatGPT y lo probé por primera vez, era escéptico. Esos primeros prompts me sorprendieron bastante: los resultados eran buenos, aunque también noté alucinaciones y respuestas algo desconectadas de la actualidad, debido al desfase entre la información con la que fue entrenado y el presente. Esto me frustró al principio, pero pronto entendí el porqué y lo convertí en un problema secundario. Cuando apareció la versión de pago, dudé en suscribirme. Me parecía cara, pero decidí darle una oportunidad. Rápidamente lo integré en mi workflow y, para mi sorpresa, noté un aumento en mi productividad nada despreciable. Supongo que muchos hemos pasado por estas fases de forma similar. Hoy por hoy, me resulta impensable cancelar la suscripci…  ( 4 min )

Your GitHub Actions Secrets Are the Weakest Link in Your AWS Security Chain Are you still using AWS access keys and secrets to authenticate your GitHub Actions with AWS in 2025? Please don't. Unless you want to wake up someday with 1000 GPU machines mining Bitcoin in your account at your expense, footing a million-dollar bill. Using long-term secrets can be a security nightmare that could expose your cloud account to a possible security incident. You might be just one exposed GitHub secret away from an AWS billing catastrophe.

Microservices promise flexibility, scalability, and faster deployments. However, without proper communication strategies, they quickly become a tangled web of tightly coupled services, frequent downtime, and frustrating bugs. In this article, we’ll explore common microservice communication problems and how to fix them by adopting modern patterns and tools. Imagine a typical e-commerce application with services like OrderService, PaymentService, and InventoryService.

Overview TypeScript is an object-oriented programming language developed by Microsoft in 2012. It is a superset of JavaScript, extending its functionality by adding data types, classes, and other object-oriented features along with type-checking capabilities. While JavaScript is ideal for small-scale applications, TypeScript is better suited for larger projects. It can be used to develop JavaScript applications for both server-side and client-side execution. TypeScript can be likened to JavaScript, but with a stricter and more organized approach. If JavaScript is your easygoing companion, TypeScript is the disciplined soldier in your coding journey. While both are capable languages for web development, TypeScript adds a layer of structure and order, making it ideal for managing large-sca…  ( 5 min )

Troubling Situation Isn’t that a bit strange? Even today, many AI startups are still focused on perfecting their chat interfaces, as if a better text box alone could unlock the future of interaction. But is that really the best we can do? Modern language models already understand complex intent — that’s no longer the bottleneck. The real challenge is that we haven’t given them a true environment to act in. Our entire digital ecosystem is still built on a core assumption: that the world is made for humans. Webpages, buttons, input fields — all designed with the idea that a person is sitting there, manually initiating and completing tasks.

Introduction: Today, I encountered a frustrating but educational error while working on a Spring Boot project in Eclipse. The error message read: "One or more constraints have not been satisfied. Utility Module and Dynamic Web Module 6.0 cannot both be selected." If you're new to Spring Boot or Maven, this might confuse you — here’s what it means and how I resolved it. Spring Boot is designed to run as a standalone JAR with an embedded server (like Tomcat). It doesn't need or support legacy Java EE modules like the Dynamic Web Module. Eclipse, however, sometimes misinterprets your project structure and adds these facets automatically, causing conflicts like: Dynamic Web Module cannot be removed Utility Module conflicts with Web Module Spring Boot controllers not working Delete Eclipse’s Facet Metadata: .settings/, .project, and .classpath from the project folder Re-import Project: File → Import → Maven → Existing Maven Project Ensure Correct Maven Configuration: jar Run the Project with: mvn spring-boot:run OR Run As → Java Application on your main class Fix the Controller: java @Controller public class HomeController { @RequestMapping("/") @ResponseBody public String home() { System.out.println("Hit HomeController"); return "Welcome to Spring Boot!"; } } ### 🔎 Lesson Learned: * Don’t use `Dynamic Web Module` with Spring Boot * Use embedded server – not external WAR deployment unless required * Always check controller method return types and annotations * Spring Boot thrives on simplicity — don’t force Java EE structures into it ### 💬 Final Words: I faced this issue for hours and now fully understand why Spring Boot doesn't need the overhead of servlet container configuration. If you're facing the same — **delete Eclipse metadata, use pure Maven, and let Spring Boot do its magic.**  ( 3 min )

Introduction Last year, I began my journey into Java programming. Like many students, I focused mainly on what was taught in the university syllabus—just enough to pass exams. I didn’t explore Java deeply, nor did I truly understand how to approach learning programming as a skill, rather than a subject. Now, I’ve decided to start over, not because I failed, but because I finally understand what I want—to become a professional Java developer who writes clean, working code and can build real-world applications confidently. When I first learned Java, my focus was limited to: Clearing university exams Memorizing definitions and syntax Completing assignments just to get grades I built a small project using Servlets, JSP, and Hibernate, but deep down, I felt unsure about how much I actually un…  ( 4 min )

Ever wondered how AI tools like ChatGPT, Siri, or Grammarly understand what you are saying and respond like a human? That’s all thanks to Natural Language Processing (NLP), a branch of Artificial Intelligence (AI) that helps machines make sense of human language. NLP sits at the intersection of computer science, linguistics, and deep learning. It’s the reason why AI can translate languages, summarize articles, answer questions, and even chat with you (chatGPT 😆). As a subfield of Deep Learning, NLP uses neural networks to process and generate human language in a way that feels surprisingly intelligent. NLP is a subfield of Deep Learning, which itself is part of the broader world of Machine Learning.

"There’s a new JavaScript framework every week." A 2024 survey of over 70,000 developers by Stack Overflow found that 60% of developers feel overwhelmed by how fast the tech industry evolves. Between React, Svelte, Qwik, Bun, Astro, Rust, Go, and a dozen more tools that popped up last month — it’s easy to feel like you're always behind. But here’s the truth no one tells you: You don’t need to learn everything. Let’s break it down. It’s a trap. You start learning React, then someone on Twitter says, “React is dead, learn Solid.js!” You're halfway through a Node.js course, and someone posts, “Why I switched from Node to Rust and never looked back.” You spend weeks learning Docker, only to see a new tool with a cooler logo take over the headlines.

What is DIP? Dependency Inversion Principle is one of the SOLID Principle. It states that High Level Module shouldn't depend on low level modules, Both should depend on abstraction. Means, the code that handles business-logic shouldn't depend directly on the implementation details. Instead they both should depend on interfaces/abstract Class. Suppose we have to 2 Modules,Car Module and Engine Module and Car Module uses Engine Module. Now if we are using DIP then we can swap Diesal Engine to Petrol Engine. Otherwise I have to make changes in the Car Module also. We can do this using either interface injection or abstract class injection.

How to Create Your Own Laravel String Helper Method Using a Macro Ibrahim Al Anshor ・ Jun 22 #laravel #php #webdev #programming  ( 2 min )

Laravel's String helper offers many useful methods you can use in your application. We can also create our own laravel string helper method using a macro. For example, I want to create a randomSlug method that turns a string into a slug and appends a random string. use Illuminate\Support\Str; Str::macro('randomSlug', function ($slug, $length = 6) { return Str::slug($slug . ' ' . Str::random($length)); }); To use the method throughout your Laravel application, register the macro in the boot method of AppServiceProvider. <?php namespace App\Providers; use Illuminate\Support\ServiceProvider; use Illuminate\Support\Str; class AppServiceProvider extends ServiceProvider { public function register(): void {} public function boot(): void { Str::macro('randomSlug', function ($slug, $length = 6) { return Str::slug($slug . ' ' . Str::random($length)); }); } } Here's how to use the custom helper in a controller. <?php namespace App\Http\Controllers; use Illuminate\Support\Str; class TestController extends Controller { public function test() { return Str::randomSlug('Hello World'); } } The output will be like this: hello-world-tn8hfd Using macros, we can create custom methods on Laravel's string helper to make string manipulation easier in a Laravel application.  ( 3 min )

Polymorphism in PHP is an object-oriented programming concept that allows different classes to be treated through a common interface or parent class. It enables you to call the same method on different objects, each responding in its own way. This promotes code flexibility and scalability, making it easier to extend functionality without modifying existing code. A common example is having multiple classes like PdfExporter, CsvExporter, and XmlExporter all implementing an export() method from a shared interface — allowing you to work with any of them interchangeably in your code. Do you find it makes your codebase more maintainable — or more complex? Have you ever replaced polymorphism with simpler conditional logic for readability? In Laravel (or other PHP frameworks), where have you found polymorphism most useful? Do you think polymorphism is overused in some PHP projects, or is it underutilized compared to what it can offer?

In part 1 I proposed a simple modification to Google’s Multi-Window Multi-Burn Rate alerting setup and I showed how this modification addresses the cases of varying-traffic services and typical latency SLOs. While my proposed solution was simply to alert on the error budget instead of the error rate, in this part I will show how we can still alert on the error rate but do it correctly. More importantly, the novel error-rate-based alert I will develop will expose a dynamic time-dependent burn rate expression which in contrast to Google’s static one leads to built-in compatibility to varying-traffic services. A certain disadvantage in my proposed solution in part 1 is that the metric which it alert on is the error budget while the metrics we care for when implementing SRE are the SLIs (or th…  ( 8 min )

Managing Observability Access with Terraform: A Deep Dive into CloudWatch Observability Access Manager The relentless growth of microservices and distributed systems demands robust observability. However, granting broad access to observability data – logs, metrics, traces – creates significant security and compliance risks. Traditionally, managing access to CloudWatch (or similar services on other clouds) involved complex IAM policies, often over-permissive and difficult to audit. This leads to a constant tension between enabling engineering velocity and maintaining a secure, compliant environment. CloudWatch Observability Access Manager (OAM) addresses this directly, and integrating it into your Terraform workflows is crucial for modern infrastructure automation. This isn’t a “nice-to-h…  ( 7 min )

Imagine you are building something with LEGOs. Components are your individual LEGO bricks (, , ). Props are the instructions you give to a brick. Hooks are special abilities you can give to a brick. Part 1: Props (How Components Talk to Each Other) The Core Idea: Props (short for "properties") are used to pass data from a parent component down to a child component. It's a one-way street: data only flows downwards. The Analogy: Ordering at a Restaurant You (the Parent Component): You are the customer ordering a pizza. The Chef (the Child Component): The chef is the component. Your Order (the Props): You tell the chef, "I want a large pizza with pepperoni and extra cheese." These specific instructions—size: 'large', topping: 'pepperoni',…  ( 6 min )

🧠 What Is Lazy Loading? 💡 Key Benefits 🛠️ How to Implement Lazy Loading in React import React, { lazy, Suspense } from 'react'; const LazyComponent = lazy(() => import('./LazyComponent')); function App() { return ( ); } 2.Route-Based Loading (React Router) import { BrowserRouter as Router, Routes, Route } from 'react-router-dom'; import { lazy, Suspense } from 'react'; const Home = lazy(() => import('./Home')); const ImagePage = lazy(() => import('./Image')); function App() { return ( } /> } /> ); } 3.Image & Component Libraries import LazyLoad from 'react-lazyload'; 4.Dynamic Imports with Buttons or Interactions const LazyProfile = lazy(() => import('./LazyProfile')); function App() { const [showProfile, setShowProfile] = useState(false); return ( setShowProfile(!showProfile)}> {showProfile ? 'Hide' : 'Show'} Profile {showProfile && ( )} ); } ✅ Best Practices Lazy-load only non-critical code - e.g., modals, routes, images. Always pair with fallback UI using Suspense. Consider preloading components likely to be used soon. Handle errors gracefully with Error Boundaries. Test on real devices and low-bandwidth connections. 🔚 Final Words Done right, lazy loading reduces initial payloads, improves perceived responsiveness, and keeps your app scalable. Done poorly, it adds complexity and brittle flows. Try adding a lazy-loaded route or image to your next React build - it could save your user seconds of load time.  ( 3 min )

Recently, I saw an announcement right here on dev.to about the Build Games with Amazon Q CLI challenge promoted by AWS. The idea is simple: use Amazon Q's AI to build a game, share how you did it, and if you're among the first 2,000 valid participants, you get an official Amazon Q t-shirt. I had already done some tests with Amazon Q before, so when I saw this challenge, I realized it was the perfect opportunity to turn an experiment into something more fun — and still walk away with a new t-shirt in the end. In fact, I had already participated in a previous initiative and shared my experience in this article here on dev.to. Instead of using just the terminal, I chose to use the official Amazon Q extension for Visual Studio Code, which makes the experience much smoother. With it, you can ta…  ( 4 min )

Yesterday, I was really excited since joining the course, wondering when we would attend a hackathon because my brother had told me that if a hackathon happens, don't miss it, attend it, you'll get good experience and learn something new. Then yesterday, I got a chance to attend hackathon. So, I woke up early in the morning and got ready to go. But suddenly, I got food poisoning, so I couldn't attend. I felt really bad. Some of my friends attended and later shared their experiences, which made me feel even worse. The day before, I had eaten chicken fried rice at a hotel in Chennai, and it didn’t suit me. My parents scolded me and told me that hereafter, I shouldn’t eat non-veg in Chennai. I spent half of the day feeling upset, then I slept well in the afternoon. In the evening, I went to the temple, then visited my grandmother’s house, had dinner there, and slept... --> That’s how my day went:)  ( 3 min )

https://github.com/CampbellSoftware/Tardigrade Hello. I am Grayson. I recently built a programming language I call Glowscript. It doesn't have a compiler yet, but runs in a tkinter script. Here is how you can use Glowscript for sorting and messing with data! PRINT Hello World Let's break it down. The PRINT function prints Hello World onto the terminal. Pretty straightforward! SET x Hello SET y World PRINT x y Let's break it down. SET sets two variables named x and y with values "Hello" and "World". Then, PRINT prints them out. SET x 0 PLUS x 1 PRINT x LOOP 2 5 Let's break it down. SET sets x to 0, and plus adds 1 to x. PRINT prints x to the console. The LOOP function goes to line 2 5 times. In other words, every time you hit LOOP, it's counter, 5, goes down by 1, and once the counter reaches 0, LOOP does nothing. If you want to learn Glowscript, go to https://github.com/CampbellSoftware/Tardigrade now!  ( 3 min )

When the CDN Blinks: Endpoint Obfuscation, TTL Conflict, and Behavioral Web Architecture By Tyler Johnston-Kent (Formant) Computational Behavioral Analyst • Indie Systems Engineer • Firebase Web Architect I built a modular, fast-loading, secure portfolio and CMS system entirely from scratch — no frameworks, no CMS, no dependencies. Along the way, I unintentionally triggered a CDN cache anomaly involving Firebase Hosting and Cloudflare, driven by endpoint obfuscation and honeypot logic. This is a case study in how behaviorally-aware web design can expose CDN TTL mismatches, detect botnet patterns, and passively observe spoofed access without intrusive fingerprinting.

Today's Task: Photo Layout and Minor Adjustments Today I worked on the photo layout for one of the sections on my LP. It was mostly about placing images and making the surrounding design elements align visually. But here’s the thing: I started laying things out without a clear, defined goal or a vivid end image in mind. I just had a general feeling, maybe something like this and went from there. Design Fatigue, or Just a Weak Idea? After spending so long on the same page, I started losing perspective. Is this layout actually good? Or am I just getting used to it? I finished a version of the section, but I couldn’t shake the feeling that it’s… just okay. Not bad, but not memorable either. And that’s a problem. If It Doesn’t Move Me, It Won’t Move the User One thing I’ve been thinking about is this: If the creator doesn’t feel anything while making it, how can we expect the viewer to feel something or take action? That’s the scary part about visual design. It's not enough for it to function; it has to connect. Tomorrow's Focus: Figure Out Why Instead of tweaking the layout endlessly, I’ll take a step back tomorrow. I want to understand why this layout doesn’t feel right: Is it the lack of contrast? Are the images too weak or generic? Is the hierarchy unclear? Am I trying to say too much with too little? I’ll try to write down a few specific reasons, no matter how small, and build from there. Design isn’t just about moving elements around. It’s about making decisions with emotion and clarity. Today I moved pieces. Tomorrow I’ll try to move meaning.

ASGI: Beyond the Web – A Production Deep Dive Introduction Last year, a seemingly innocuous deployment of a new microservice responsible for real-time feature flagging triggered a cascading failure across our core platform. The root cause wasn’t a code bug in the feature flag logic itself, but a subtle deadlock within the ASGI server handling the persistent WebSocket connections. The server, under sustained load, was exhausting its event loop resources, leading to unresponsive services and ultimately, a partial outage. This incident highlighted a critical gap in our understanding of ASGI’s intricacies and the importance of careful resource management in async Python applications. This post aims to share lessons learned from that incident and provide a comprehensive, productio…  ( 7 min )

Oi, gente! 👋 Quero compartilhar uma ferramenta que conheci recentemente e tem me ajudado demais a criar laboratórios para estudar Linux: o Vagrant. Basicamente, o Vagrant automatiza a criação e o gerenciamento de máquinas virtuais. Mas atenção: ele não cria a VM sozinho — ele precisa de um provedor para isso (tipo VirtualBox, VMware, Hyper-V, Docker...). Para este exemplo, vou usar o VirtualBox, e todos os comandos foram feitos pelo PowerShell, no Windows mesmo. Primeiro, baixe e instale essas duas coisas: VirtualBox Vagrant Depois que instalar tudo, abra o PowerShell (pode usar o atalho Win + S, digitar "powershell" e abrir como administrador).

Diving Deep into Node.js dgram: Production UDP for the Pragmatic Engineer Introduction We recently encountered a challenging scaling issue with our internal event notification system. Built as a REST API, it was struggling to handle the sheer volume of low-latency, one-way notifications required by our microservices architecture. Each service needed to broadcast events (e.g., “order created”, “user updated”) to interested subscribers without requiring a response. Polling was unacceptable due to latency and resource consumption. WebSockets were overkill for this simple broadcast pattern. This led us to revisit UDP and Node.js’s dgram module. This isn’t a “first look at UDP” post; it’s about how to leverage dgram in production Node.js systems where reliability, scalability, a…  ( 7 min )

The root cause wasn’t a DDoS attack, but a lack of proper connection queue tuning and insufficient resource allocation on the proxy server. This incident, and countless others, underscore the critical role proxies play in modern network infrastructure. Proxies are no longer simply about circumventing firewalls or caching web content. They are foundational components in hybrid/mu…  ( 7 min )

Hello, folks! 👋 Vagrant. At its core, Vagrant automates the creation and management of virtual machines. But here's a crucial point: it doesn't create the VM on its own.

Static Methods in JavaScript: Beyond the Basics Introduction Imagine you’re building a complex data visualization library for a financial trading platform. Users need to perform a variety of statistical calculations on time-series data – moving averages, standard deviations, correlation coefficients. Each calculation requires a specific algorithm, but doesn’t inherently belong to any particular instance of a TimeSeries object. Attaching these calculations as instance methods would be semantically incorrect and lead to unnecessary object creation and method lookup overhead, especially given the high-frequency nature of trading applications. This is where static methods become invaluable. They provide a clean, performant, and logically sound way to encapsulate utility function…  ( 7 min )

I have started to create a new open source project called EXSQL, which is a direct improvement to SQL, adding more modern enhancements and better syntax for complex applications. Enhanced and eXtended Structured Query Language is actually a transpiler (like JSX), which seeks to improve SQL by simplifying tasks and improving the syntax, such as inheritance in databases, making it a rather complicated and exhausting task, instead, thanks to EXSQL we could do something like “SUBTYPE OF” in a CREATE TABLE and it would generate all the necessary logic for the database but we would be using EXSQL to do everything.

There was a time when I could stare at a blank terminal, summon a coffee-fueled epiphany, and build things from scratch. Today, I stare at my editor—and ChatGPT stares back. AI didn’t just assist my workflow—it took over it. What started as a helpful little sidekick for debugging soon became the architect, planner, and even the copywriter for my commits. Want to center a div? “Hey ChatGPT, give me a Tailwind class to center this.” Need to write a CRUD API? “Write me an Express.js API with MongoDB and JWT auth.” Stuck on a bug? “Here’s the error log, now fix it.” And it works. Every time. Which is great… until you realize your brain hasn't written a loop by hand in weeks. There’s something oddly dystopian about knowing how to write something but choosing not to. I still understand clo…  ( 4 min )

The Ubuntu Kernel: A Production Deep Dive Introduction A recent production incident involving high latency on a critical database server traced back to a subtle kernel regression in the network stack. Specifically, a change in the TCP congestion control algorithm introduced in a recent kernel update was exacerbating packet loss under heavy load, leading to application timeouts. This isn’t an isolated event. Modern Ubuntu-based infrastructure – whether cloud VMs, on-prem servers, or containerized environments running long-term support (LTS) releases – relies heavily on a stable and performant kernel. Ignoring kernel-level details is no longer a viable option for maintaining reliable, scalable, and secure systems. This post dives deep into the Ubuntu kernel, focusing on practic…  ( 6 min )

We live in the era of hyperconnectivity. As a developer, I spend at least 8 hours a day in front of a computer. At 39, having recently transitioned from an executive role to the tech field, I understand this is part of my job. The problem isn’t screen time at work — it’s what happens afterward. In my free time, instead of disconnecting, I dive into mobile games, scroll Instagram almost on autopilot, and binge-watch YouTube videos. I have an 8-year-old son, and every time I see him imitating my habits, I feel a deep discomfort. Because in the end, it's not what we say — it's what we do that shapes who they become. This routine, though common, is far from harmless. 🌟 The Reality: Data on Tech Dependency and Burnout A Harvard Business Review study showed that 68% of developers have experienc…  ( 4 min )

I used to think handling errors in GraphQL was straightforward. Your query would return data and errors fields and you would use that to display the relevant information to the user. But it goes a little deeper than that. We're going to look at the different kinds of errors and how we take advantage of the __typename field. Say you have a mutation for when a user signs up: mutation signUp($input: SignUpInput!) { signUp(input: $input) { user { id email name } } } And from our app we might do something like this: const [signUp, { data, error, loading }] = useMutation(signUpMutation) if( error ) { // do something } const onSubmit = async (formData: FormData) => { await signUp({ variables: { input: { email: formData.email, password…  ( 5 min )

The concept of memory is very important in Javascript and today we will deep dive into this. At the end this concept of memory allocation will be helpful to understand another important concept of serialization and deserialization. Primitive values are immutable and have a fixed size, so they can be easily stored and accessed in the stack. Objects are mutable and have a variable size, so they need to be stored and accessed in the heap, which is more flexible but also slower. let fname = "John"; // string literal, stored in stack memory let lname = "Doe"; // string literal, stored in stack memory let newfname = fname console.log(`First Name: ${fname}, Last Name: ${lname}`); // Accessing string literals from stack memory console.log(`New First Name: ${newfname}`); // Accessing new variable…  ( 7 min )

In many codebases, inheritance is still the default tool for reusing behavior. But in real-world, evolving systems, inheritance often brings more rigidity than flexibility. Composition offers a significantly more adaptable and maintainable alternative. Inheritance implies an “is-a” relationship between objects. While this seems clean in theory, it quickly leads to practical problems: Rigid hierarchies: Behavior is locked into base classes and difficult to adjust without side effects. Tight coupling: Subclasses depend heavily on base classes. A small change in the base can ripple through the system. Low reusability: Behavior is tied to a particular class hierarchy and hard to extract or share. Poor maintainability: Deep inheritance trees obscure behavior and make debugging harder.

Hi everyone! 👋 If you're like me, you love automating the little things — especially when it comes to DevOps workflows and release management. One of those things that used to be... well, a little annoying was letting a team (or community) know when a new release dropped. So I built Releasify Action — a lightweight GitHub Action that instantly notifies your Discord server whenever a new release is published.

🚀 Why I Switched from Framer Motion to GSAP 🧠 Context But once I began working on more motion-driven projects like: 🧬 DOM + Canvas hybrid UI 🎯 Interactive landing pages 🪐 Scroll-based 3D storytelling (with Three.js) …I started hitting walls. Syncing animations. Handling scroll. Cross-platform support. That's when I discovered GSAP. ✅ What GSAP Does Better (And Why I Use It Now) 🎬 Real Timeline Control With gsap.timeline(), you get frame-accurate sequencing. Overlaps, delays, sync — all with fine-tuned control. Framer has no true timeline system. Syncing multiple variants across components gets messy fast. 🧩 Animate Anything CSS, SVG, canvas, scrollTop, clip-path, even JS objects — GSAP handles it. Framer is limited to props like x, opacity, scale, etc. 🌍 Platform-Agnostic GSAP works with DOM, SVG, WebGL, Three.js, and plain JS. Framer Motion = React only. 📐 Unit Flexibility px, %, vw, em, --css-vars — GSAP understands them all, no need for manual conversion. Framer often requires workarounds or state calculations for dynamic units. 🌀 ScrollTrigger (Built-In) Scrub animations Pin sections Media-query-based motion Timeline-on-scroll Framer needs third-party observers and tons of glue code. 🚀 Performance GSAP is written in vanilla JS and optimized with direct requestAnimationFrame.

The Problem That Started It All ConvertAPI: $30/month for 1,000 conversions Wait, what? Node.js + Express Conversions Supported: Markdown ↔ HTML The entire backend is maybe 6-700 lines of actual conversion logic, and tons of plugins I configured. The rest is authentication, rate limiting, billing integration, and error handling. My pricing: 100 free conversions/month That's roughly $0.0012 per conversion vs the industry's $0.03. Sometimes when you say to yourself " I could do this better" You are right. A lot about securing a service, this is my first SaaS project, but hardly my first JS one. Sometimes things cost way more than they need to, this is running on a small vps, but if people use it I will upgrade to keep performance great. The overhead is pretty minimal. Time sink: This was supposed to be a weekend project. It's been weeks. Support burden: Users expect enterprise reliability at indie prices Market risk: Competitors could drop prices tomorrow Opportunity cost: Could have built something more innovative But sometimes it's worth it if: The pricing gap is truly absurd (25x counts) The Results So Far Live for a day. Users signing up.Product Hunt pending. More importantly: I learned that sometimes the "impossible" competitive landscape just needs someone willing to charge reasonable prices.

By default, when the Enter key is pressed in a form's input field, it will trigger the form to be submitted. This behaviour can be prevented with JavaScript — here's how: Listen for key presses in the input using the keydown event. Check the key pressed by reading the key property of the event object. If the key is Enter, prevent the default behaviour (triggering form submit) by calling preventDefault method on the event object. For example: document.querySelector('input') .addEventListener('keydown', (e) => { if (e.key === 'Enter') { e.preventDefault(); } }); This way, every time Enter is pressed in the form's input field, the form won't be submitted.  ( 3 min )

I have recently done two maintenance releases of the GitHub action for checking spelling. 0.50.0 on 2025-05-16 0.51.0 on 2025-05-20 I did one as the base image was updated and could might aswell ship it, since not much else was planned. From the change log for 0.50.0: Docker image updated to Python 3.13.4 slim via PR #246 from Dependabot. Release notes for Python 3.13.4 A few days after a PR for updating the base image again came in. From the change log for 0.51.0: Docker image updated to Python 3.13.5 slim via PR #249 from Dependabot. Release notes for Python 3.13.5 Release 0.49.0 was made on 2025-05-22 and prior to that 0.48.0 on 2025-04-01, so I was satisfied with the monthly cadence of releases. But the world around us changes constantly, so I thought I might as well keep up and get the chore done. For myself this results in a bunch of PRs to review and merge, next week when Dependabot notifies me of the 0.51.0, but I can live with that and I can handle it on my commute to work on the phone. I hope it is not too much inconvenience for the other users of the action.  ( 3 min )

When you're learning React, one concept you’ll often come across is props drilling. At first, it might seem confusing—but once you understand what’s happening, it’s quite straightforward. Let’s break it down. Props Drilling is when you pass data from a parent component down to deeply nested child components using props—even if the intermediate components don’t actually need that data. This often leads to bloated and harder-to-maintain code, especially in large apps. Imagine you have this component structure: App → Parent → Child → GrandChild Now, let's say App has some data that GrandChild needs. Here’s what props drilling would look like: function App() { const user = "Tamilselvan"; return ; } function Parent({ user }) { return ; } function Child({ user }) { return ; } function GrandChild({ user }) { return Hello, {user}! ; } Notice how Parent and Child don’t use the user prop, but they still have to pass it along just so GrandChild can use it. That’s props drilling. Hard to maintain – Changing the data structure means updating multiple components. Cluttered code – Components get unnecessary props. Performance issues – Every component in the chain re-renders when the prop changes. React Context API Share data across components without manually passing props. const UserContext = React.createContext(); function App() { return ( ); } function GrandChild() { const user = useContext(UserContext); return Hello, {user}! ; } State management tools Like Redux, Zustand, or Recoil for large-scale apps. Props drilling isn’t always bad—it’s just a sign that your app might need a better way to manage shared state. For small apps, it’s totally fine. But as your component tree grows, learning tools like Context API becomes essential.  ( 4 min )

The Unsung Hero: Mastering Callbacks in Production Node.js Introduction We were onboarding a new payment processor into our microservices architecture. The processor’s Node.js SDK relied heavily on callbacks for asynchronous operations – specifically, handling webhooks for transaction status updates. Initial integration attempts resulted in intermittent failures, lost updates, and a cascade of support tickets. The root cause wasn’t the processor’s SDK itself, but our team’s insufficient understanding of callback management in a high-throughput, distributed system. This isn’t an isolated incident. Callbacks, while foundational, are often treated as a solved problem, leading to subtle but critical issues in production Node.js applications. This post dives deep into callbacks, …  ( 7 min )

Hi there! I’m Kaden, a 16-year-old developer building an AI assistant called CODA: A Creative Optimization & Development Assistant. CODA is designed to create, edit, and optimize code by analyzing your entire project—because it actually has local access to your files. This means it can give advice that makes sense in the full context of your work, not just a single file or snippet. I started building CODA a couple of weeks ago, and I’ll be honest—I'm not some genius. I used ChatGPT a lot to help write the code. But soon, I hope to rely on CODA alone. Right now, I'm in Phase 2, where CODA can read all files in your project, understand and generate code based on the full context, and offer targeted coding advice. My plan for the future is to make a smart debugger, an improved memory system (because I'm currently using .json files), Text-to-speech, speech-to-text, and even a wake word so it starts feeling more like JARVIS. If you'd like to stick around, I’ll be posting another update when Phase 2 is complete, and outlining the roadmap for Phase 3. Thanks for reading! Let me know what you think, and if you know any ways I can optimize my progress, I'd love to hear them.  ( 3 min )

As a developer who has lived and breathed React for years, I've always been skeptical of new frameworks promising to be "the next big thing." But the buzz around Svelte and SvelteKit finally got to me. I spent a weekend rebuilding my portfolio with it. Here are three "aha!" moments that genuinely surprised me. The Disappearing Framework State Management is Just... JavaScript let count = 0; function handleClick() { That's it. This simplicity felt almost too easy at first, but it's incredibly refreshing. File-based Routing Feels Like Cheating SvelteKit's file-based routing (similar to Next.js) is a joy to work with. Creating a new page is as simple as creating a new +page.svelte file in your routes directory. Loading data for that page is done in a sibling +page.server.js file. It's intuitive, co-located, and makes the entire structure of the app easy to reason about. I'm not abandoning React tomorrow, but my skepticism is gone. SvelteKit offers a fantastic developer experience and incredible performance. If you're a React dev on the fence, I highly recommend giving it a try. What are your thoughts on SvelteKit?  ( 4 min )

So I was working on some benchmarking with a piece of code in JavaScript and I was scratching my head over the runtimes that I was seeing. I literally could not make sense of what was happening. And in a wild attempt at debugging, I stumbled upon a quirk that I had never known. The v8 engine does not really like the delete operator. And using this operator on an object can have a tangible impact on the performance of your code. In my case, it was almost 3 times worse performance than if I had manually set that key to undefined or false That said, I was able to reproduce this in Safari v18.5 as well along with all Chromium based browsers. So not really sure if this behavior is limited to the v8 engine. Here’s a simple code I wrote based on my experience to easily benchmark the performance i…  ( 4 min )

🐙 GitHub Pattern matching in TypeScript has become an essential part of my daily workflow, both in React and Node.js. Personally, I haven't found a need for switch-case statements—I can't even recall the last time I used one. In this post, I'll share practical pattern matching techniques that I rely on regularly. All the reusable code can be found in the GitHub repository. Often, when we reach for a switch-case statement, our real goal is to run different logic depending on the value of a union type or enum. For example, in a music theory app, we need to generate different note patterns for different scale types. Each scale type—like blues, full, or pentatonic—has its own function that implements the specific logic for that scale, but all of these functions share the same input and output…  ( 11 min )

Understanding Functional Programming Functional programming is a programming style or paradigm that focuses on building software by creating and combining functions. Think of it like this: you write small, self-contained pieces of code (functions) that take an input, perform some operations, and then produce an output. A core idea is that for the same input, you will always get the same output, making the code predictable. Reusable: Functions are designed to be independent, meaning you can easily reuse them across different parts of your code or in various modules, as long as you need their specific output. Stateless: Functional programs aim to be "stateless." This means a function's output depends solely on its inputs, not on any changeable internal or external state. No matter how man…  ( 6 min )

Ever looked at your code and thought, “There must be a better way to organize this.” That’s where design patterns come in. In this post, we will explore what design patterns are, why they matter, and how they are categorized. Design patterns are proven, reusable solutions to common software design problems. Think of them like templates or blueprints—not code that you copy and paste, but rather ideas and structures that guide you in solving recurring problems in a clean, efficient, and maintainable way. Design patterns generally fall into three broad categories, each addressing a different kind of software design problem: 1. Creational Patterns object creation mechanisms, trying to create objects in a manner that is suitable to the situation. They help make a system independent of how its objects are created, composed, and represented. Examples: Singleton, Factory Method, Builder, Abstract Factory, Prototype 2. Structural Patterns composed to form larger structures. They help ensure that if one part of a system changes, the entire system doesn't need to do the same. Examples: Adapter, Composite, Proxy, Decorator, Bridge, Facade 3. Behavioral Patterns communication between objects, focusing on the responsibilities and the flow of control in a program. Examples: Observer, Strategy, Command, State, Iterator, Mediator In the upcoming posts, I’ll break down each design pattern—complete with real-world analogies, use cases, pros & cons, and practical examples in code. Whether you’re a beginner developer or someone brushing up on architectural skills, this series will help you think more clearly about software design. Have you used any design patterns in your projects? Or do they still feel abstract and academic? Drop a comment below—I’d love to hear your thoughts or questions!  ( 3 min )

"Replaying 10,000 events just to check a balance? There’s a better way." Event sourcing gives you time-travel superpowers—until you realize: Rebuilding an aggregate from 1M events takes minutes. Your read API times out waiting for a replay. Testing becomes painfully slow. Snapshots fix this by periodically caching state, so you only replay recent events. Here’s how to implement them without breaking event-sourcing principles. 1. When Do You Need Snapshots? Problem Signs Slow reads: GET /users/123 triggers a 5-second replay. High memory usage: Event processing OOMs your pods. Frequent replays: The same aggregate is rebuilt repeatedly. Rule of Thumb Snapshots make sense when replay time > 100ms for hot aggregates. 2.

Securing the Edge: A Deep Dive into IBM Bluemix Ti Board Starter Imagine a global logistics company, tracking thousands of containers across oceans and continents. Each container is a potential security risk – tampering, theft, or environmental damage. Traditional security measures are often reactive, relying on inspections at ports. Now, envision a system where each container actively reports its status, location, and integrity in real-time, triggering alerts the moment something is amiss. This is the power of edge computing, and securing it is paramount. IBM Bluemix Ti Board Starter is a key enabler for this kind of proactive, secure edge deployment. Today, businesses are increasingly adopting cloud-native applications, embracing zero-trust security models, and navigating the complexi…  ( 11 min )

Seu sistema está lento, travando sob carga ou apresentando falhas em cascata? Um dos culpados pode ser a ausência de um mecanismo crucial: Back Pressure. Em sistemas distribuídos, componentes se comunicam constantemente. Um producer (upstream) envia dados para um consumer (downstream) processar. Mas o que acontece quando o producer é muito mais rápido que o consumer? O consumer fica sobrecarregado, sua fila de processamento explode, a memória estoura e o sistema inteiro pode cair. É aqui que entra o Back Pressure. Back Pressure é um mecanismo de feedback que permite ao componente consumer (sobrecarregado) sinalizar ao producer (rápido demais) para que ele diminua o ritmo ou pare de enviar dados temporariamente. Pense nisso como um controle de tráfego. Em vez de deixar os dados fluírem sem …  ( 5 min )

Project Structure Overview and Login Flow In part one, we gained an overview of the directory structure and the packages we will install for the project. Now, we’ll discuss the login flow, which will be implemented as follows: Opening the App: If the user is not logged in: Display the Login Screen. The user taps “Login with Apple” to initiate the login process on their iPhone. 2. Searching for the User based on the account: If the user does not exist: Create a new user and proceed. If the user exists and is valid: Retrieve the valid user information and proceed. If the user exists but is invalid: Display an error. 3. Returning to the App: Store the login information in Context. If the user is valid, navigate to the Home Screen. If the user is invalid, navigate to the Error Screen. 4. W…  ( 8 min )

In existing logging libraries, including Go’s built-in log/slog logging library, they typically support log file rotation and splitting. However, these features are not built in directly—they need to be actively configured by us to enable them. This article will explore several popular logging libraries, such as logrus, zap, and the official slog. We will analyze the key design elements of these libraries and discuss how they support the configuration of log rotation and splitting. When comparing the design of logrus, zap, and slog, one prominent commonality is that they all include the crucial property of io.Writer. This property plays a central role in the design of logging frameworks, as it determines the target location for log output. logrus is a feature-rich logging library for Go, p…  ( 7 min )

LeetCode, Codewars, and similar sites that "test your skill" as a developer aren't good interview tools, but they can be good personal skill builders. Rather than highlighting developers who can follow direction and solve problems, using sites like these as skill-validation tools can strongly favor developers who memorized the answer rather than developers who can demonstrate skill in reading requirements, following instructions, and solving problems. Don't get me wrong; knowing the answer is an important part of development. Not reinventing the wheel saves us time, complexity, and risk. But there are different aspects of the role of developer, and knowing about a linked list is different than demonstrating the ability to recreate one while racing a clock. As a personal development tool, s…  ( 4 min )

This is a submission for Frontend Challenge - June Celebrations, CSS Art: June Celebrations. World Sea Turtle Day (June 16) celebrates these ancient mariners who have navigated Earth's oceans for over 100 million years. Sea turtles are incredible creatures that face numerous threats, from plastic pollution to climate change. This CSS art honors their graceful swimming patterns and the underwater world they call home. Journey This piece challenged me to recreate the elegant motion of sea turtles gliding through water. I used CSS animations to simulate their distinctive swimming pattern - the way they gracefully move their flippers in a synchronized rhythm. The turtle shapes are created entirely with CSS, using clever combinations of border-radius, transforms, and pseudo-elements. The underwater environment features floating seaweed created with CSS animations and a gradient background that mimics the way sunlight filters through ocean water. I experimented with different animation delays to make each turtle move independently, creating a more natural scene. What I'm most proud of is the organic feel of the animations - they don't feel robotic or mechanical. The turtles seem to truly "swim" through their digital ocean. In future iterations, I'd love to add bubbles, more diverse marine life, and perhaps simulate the turtle's journey from nest to ocean.  ( 3 min )

At Tigris Data, we provide object storage to our users. People put bytes into our servers with a name, and expect that come hell and high water, when they put in the name, they get the exact same bytes back. This is a very high trust position to be in because when people ask themselves things like “Oh, what would happen if my object storage provider is unreliable”, that conversation usually involves phrases like “Maybe we should have gone with The Big Cloud afterall”. Such conversations are rarely good for the business. If you store your data in Tigris, you shouldn’t need to worry about a status page full of green checkmarks or anything else that needs to be updated manually. As a result, we’re trying something different. We’re making our internal reliability and performance metrics publi…  ( 5 min )

This is a submission for the Runner H "AI Agent Prompting" Challenge I built a super simple but surprisingly useful Runner H agent called “Meeting to Google Docs”. The goal? Just type in the details of your meeting, and boom — Runner H creates a clean, ready-to-use Google Doc titled with the meeting name and structured with your agenda. This agent is for anyone (like me!) who constantly has to jot down meeting notes, agendas, or brainstorms and just wants to skip the repetitive formatting and file creation. It takes 10 seconds instead of 10 minutes. runner.hcompany.ai How I Used Runner H Here’s how I set it up: Runner H instantly created a well-formatted Google Doc in my Drive — no extra clicks, no templates, no chaos. You can easily replicate this by typing your own meeting title and points — that’s it! No code, no learning curve. If you’ve ever scrambled 2 minutes before a call to create a doc, or juggled messy notes across apps, this is your fix. It’s great for: It doesn’t try to do everything — just one thing really well. And that’s the magic. ✨ I’ll be sharing this on Twitter and LinkedIn soon — will update with links here once it’s live!  ( 3 min )

The world of modern web development is evolving. Now we're not talking about the notorious race of everyday emerging front-end frameworks or about the environments that have walked the path from text editors to powerful plugin-rich and adjustable IDEs for any purpose.

As I continue my journey through the world of Web3, I’ve been digging into the building blocks that make privacy-first platforms like Midnight possible (you can catch up on previous posts in the Midnight Dev Diaries!). This week, I focused on two foundational pieces that go hand in hand: smart contracts on Midnight and the Compact language that powers them. Smart contracts aren’t new to blockchain, but Midnight’s approach is unique. Instead of executing code directly on-chain, Midnight uses smart contracts to define rules that are enforced off-chain through zero-knowledge proofs. At the center of this system is Compact—a purpose-built language designed to make writing these privacy-preserving contracts both secure and practical. To better understand how this works in practice, I also worke…  ( 7 min )

TL;DR: Borderlands 4 has dodged the dreaded $80 launch price, with its standard edition up for pre-order at $69.99 ($60/€70) ahead of its Sept. 12 release. Deluxe and Super Deluxe bundles will set you back $100 and $130, respectively, packing in post-launch DLC, skins and extra Vault Hunters. A bit of drama preceded the reveal: CEO Randy Pitchford’s flippant “If you’re a real fan, you’ll find a way to make it happen” comment on X sparked outrage, especially after he noted production costs had doubled since Borderlands 3. He’s since celebrated the $70 price on social media—some suspect it was a cheeky PR play to juice pre-orders—while other big publishers (cough Microsoft) are already eyeing $80 tags on upcoming titles.  ( 3 min )

TL;DR: Alien Ant Farm are bummed their hit “Wish” didn’t make the Tony Hawk’s Pro Skater 3+4 remake soundtrack, even though it was a fan fave in THPS4. Guitarist Terry Corso says it’s a shame they got the cut, and vocalist Dryden Mitchell reckons a more eclectic mix would’ve been cooler. Tony Hawk himself took the L, explaining he wanted players to “discover” some fresh tunes alongside the classics. The game still brings back bangers like Motörhead’s “Ace of Spades,” adds new parks (and even Michelangelo from TMNT), and drops July 11, 2025 on PC, PlayStation, Xbox and Switch.  ( 3 min )

Sony’s much-maligned live-service shooter Concord (shut down just two weeks after launch) is officially blamed on “a hyper-competitive market” and not standing out—an excuse that glosses over its awkward character designs and $40 price tag that fans hated. Now CEO Hermen Hulst promises Bungie’s next extraction shooter, Marathon, won’t repeat those “mistakes,” even though it’s already drawing flak for bland heroes, a paid model, rumored marketing cuts and internal studio drama. It feels more like Wall Street window-dressing than genuine course correction.  ( 3 min )

• Introduction Mr. Uba Joseph Ugochukwu and his team in the “From Zero to Hero” python class, was my first time of hearing “The Zen of Python”. I had to do my research before I understood what it means. In a nutshell, it’s a list of 19 short rules that help Python programmers write better codes. These rules were written by Tim Peters, and they are easy to understand but full of wisdom. Here are 4 of those rules that really speak to me, and why I think they are important in my journey: Simple is Better Than Complex. Readability Counts. Errors Should Never Pass Silently. “wow, so I’m going to be a good fit in cybersecurity after learning python”. This means that if something goes wrong in my program, I shouldn’t just ignore it. It’s better to show an error or fix it right away. So, by the end of this program, I’ll learn to write python codes without letting errors pass silently, as well as getting me ready for cyber jobs. There Should Be One — And Preferably Only One — Obvious Way to Do It. “there are many ways to kill a rat”. Yes, but there’s still that one preferable way that’s very obvious to kill a rat, depending on the situation on ground. This means it’s better to have one clear way to do a task in Python. Too many ways can be confusing. I can’t wait to work in teams or on security tools and apply this principle after this program. One clear method is better than many confusing ones. Conclusion Black Python Dev for their partnership and support for making this mentorship possible. Now, let the journey begin!  ( 5 min )

This is a shortened version of an article originally published on my blog. You can find the full version here). We all love ULIDs. They're sortable, unique enough for most purposes, and a great alternative to UUIDs. The spec is pretty clear on how to handle things, but there's one edge case that's worth talking about: what do you do when you generate so many ULIDs in the same millisecond that you run out of random bits? The official spec says to throw an overflow exception. And while that's a valid, by-the-book answer, it's not always the most practical one. In a high-throughput system, throwing an exception is a failure condition. It's something you want to avoid. So, in our C# ULID library, ByteAether.Ulid, we took a different path. When the 80-bit random part of the ULID overflows, we just increment the 48-bit timestamp by one millisecond. Here’s why we think this is a better approach for real-world applications: No More Overflow Exceptions! 🙌 This means more reliable systems, especially when you're generating a ton of IDs. Performance for the Win. 🚀 We sidestep the performance hit that comes with exception handling and other workarounds. Keep Calm and Sort On. Your IDs will still be perfectly sortable within a single process. We know this is a documented deviation from the spec. But let's be real: cross-process millisecond ordering is already a bit fuzzy. A one-millisecond bump to the timestamp in a rare overflow situation is a small price to pay for a more resilient and performant system. Check out ByteAether.Ulid on GitHub and see what you think. We're betting that for most developers, this pragmatic approach to ULID generation is the way to go.  ( 4 min )

🔹 Problem: 3443 Maximum Distance After K Operations Difficulty: #Medium Tags: #Greedy, #PrefixSum, #Simulation You're given a string of directions like 'NSEW'. You can change up to k of them into another direction. After walking according to this possibly modified path, what's the maximum Manhattan distance you can end up from the origin? Brute Force Idea: k changes to see what gave the farthest point, but that's exponential. Optimized Strategy: count occurrences of N, S, E, W, then try to convert S into N (or vice versa), and similarly for E/W, to maximize directional imbalance. I even understood that converting S → N boosts distance by +2... k changes between axes, so I looked up the solution. Algorithm Used: ⚙️ Code Implementation (Python) class Solution: …  ( 4 min )

Deploying a Python app on Google Cloud Run with Graphviz visualizations can trigger: graphviz.backend.execute.ExecutableNotFound: failed to execute PosixPath('dot'), make sure the Graphviz executables are on your systems' PATH This happens because Cloud Run’s default build misses the dot executable, even with a Dockerfile. Here’s a quick fix. Step 1: Set Up Dockerfile Create a Dockerfile to install Graphviz: FROM python:3.11-slim WORKDIR /app RUN apt-get update && apt-get install -y graphviz COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt COPY . . CMD ["bash", "-c", "dot -V && python app.py"] Uses Python 3.11 and installs dot. Add graphviz to requirements.txt manually.

Straight to the point — whenever I build a system, the very first thing I implement is a health check for all critical infrastructure components. I ping the database. I ping Redis. Just simple, lightweight checks. They may seem minor, but skipping them can lead to serious consequences. At best, you get a false sense that everything is working fine. At worst, the system enters an inconsistent state that's painful to debug and even harder to recover from.  ( 3 min )

As a mobile app developer, I’ve written thousands of lines of code across Native and Hybrid platforms—Kotlin, Flutter, React Native. But what fuels my work isn’t just technical curiosity—it's the impact. Each app I work on is a chance to solve problems—helping someone land a job, enabling a small business to grow, or bringing learning to remote areas. I believe we should talk more about tech with empathy. Tools evolve, but the mission remains: build with purpose. 🛠️ Let’s create more than just applications—let’s build change.  ( 3 min )

Data comparison between databases of different types means comparing data between two tables having same logical structures in different types of databases to find the differences. The difficulty of data comparison needs to overcome is the differences of data types and the data processing approaches between different database products. The problem is that different results will be obtained after the same data is imported to and exported from different databases. Common data types mainly include numeric, string and date. Now we use Oracle and MySQL to respectively create data tables that both contain all the three commonly seen data types and have same simple logical structure, compare differences of the two databases, and explain how to compare data between different types of databases usi…  ( 6 min )

Let’s cut to the chase: “Move to the cloud” is the tech mantra you hear everywhere in the U.S. From Silicon Valley startups to small-town mom-and-pop shops, it’s like everyone’s racing to get their data online. But here’s a reality check: the cloud isn’t a magic bullet for every business. It’s awesome—don’t get me wrong—but it’s not always plug-and-play. If you’re a small business owner in Texas, a freelancer in Ohio, or a startup founder in California, jumping in without a plan can lead to frustration. So, who needs to think twice before going all-in on the cloud? And more importantly, why might it still be worth considering? Let’s dive in. 1. Stuck with Shaky Internet?

A Meeting in the Circuit Desert The Gum That Outlived Floppy Disks Memory Stick📀, born in 1998 on a tech planet called Earth. Let me decode its story: Variants: PRO Duo: Smaller, faster (32GB max), used in PSPs and cameras—like a sparrow in a world of eagles. Fun Fact: Shaped like gum, but it won’t melt in your car (unlike floppy disks, which dissolved like sugar in rain). “Why gum?” I asked. The Rose of a Closed Garden VAIO laptops, PSPs. No other flowers allowed. How to Love a Forgotten Star (In 2025) Adapters: Use a $5 “PRO Duo to SD” adapter—like teaching a cactus to grow in a new pot. Plug it into your laptop, and voilà: it speaks modern. “Do you miss the old days?” I asked. Where to Find a Memory Stick (2025 Edition) New: Amazon or B&H Photo (Sony still sells them for industrial clients—like a baker keeping a rare recipe). Pro Tip: A 32GB Memory Stick costs $50? Walk away. It’s not gold—it’s just a gum-shaped star. The Tale of Two Planets Capacity: SD holds 2TB (a mansion), Memory Stick 32GB (a cozy hut). “Why do people still choose you?” the SD card asked. The Star That Still Lights Up Skies Medical: Stores patient data in Sony MRI machines—steady as a heartbeat. Burn Alert: The Secret of the Gum-Shaped Star Written by a wanderer who once mistook a Memory Stick for gum. (Spoiler: It didn’t taste good. But it lasted longer.) 🌵 You become responsible, forever, for the stars you once loved.  ( 5 min )

Нашел аналог гита, называется jj. Первый вопрос, который возникает после быстрого чтения описания и доки: зачем? Чем меня не устраивает гит? Идеальный инструмент, рабочая лошадка, не заваливает уведомлениями по поводу "У НАС НОВАЯ ВЕРСИЯ", хотя поддерживается и регулярно обновляется. Эта новая VCS написана на расте(модно), ну допустим, что она даже быстрее гита. Но гит не медленный: с точки зрения моего подсознания, которое делит все действия на мгновенные и долгие, все команды гита выполняются мгновенно. Не знаю, как можно использовать эти несколько выигранных долей секунд. И вот не помню, обсуждал ли я с кем-то гит, это же неинтересно. Даже не задумывался о нём ни разу, он просто выполняет свои задачи. При этом гит все знают, он известный. Каждый раз вводя в терминал короткое и удобное название пше git, его легко запомнить. А вот название непонятного сайта, на который вы забрели в поисках стоковой картинки и который миллион раз потыкал в экран своим огромным логотипом и названием, запомнить очень сложно. Можно вспомнить ещё несколько таких продуктов, их все объединяет вот эта простота работы. Вау-эффект в начале не обязателен, а в моем опыте вообще чаще говорит о перегруженности продукта фичами. Я понимаю, что корреляция это не причинно-следственная связь, но вот такое интересное наблюдение, и очень хочется, чтобы все продукты, были такими.  ( 3 min )

Hey dev.to community! In continuation to my previous post, where I mentioned about working on building Products app, CRUD operation related to Products. Now, here is the current progress that I wanted share with you all: Create a Category model. Modified the existing Product model to add category as Foreign key field. Applied Database migration. Added Category serializer, with a addon serializer method inside the respective serializer class to get product count for a particular category. Modified Product serializer to show category info as nesting category serializer. Created APIs to handle CRUD operation on Category. Registered both Product and Category models on Django admin interface for easy data management. Created superuser and interacted with Django Admin interface. While applying database migration, I encountered an issue as I have some data already added as Products. And no data under Category were available. Here is how I solved this(definitely with the help of prompting LLM): Deleting migration file which got created when executing makemigrations command. Commented out category field(Foreign key) in Product model. Applied migration only for creating Category model in Database. Then added data in Category model using shell command. Uncommented, category field(Foreign key) in Product model. Applied migrations again, it asked for some default value to be added in category field in existing product data. Chose the option 1. And issue sorted. I believe, there can be other ways to sort this issue. Overall, it was a great experience to till now and hoping to keep going like this. Attaching ss of Django admin panel. Next, I will be working on User Authentication. See you next time..bye👋  ( 3 min )

Reclaim your focus with a distraction-free Jira experience As a regular Jira user, I often found myself losing focus.

Introduction There are many ways to invest in crypto. Some try to catch the "bottom" and go all-in, others trade based on candlesticks and indicators. And then there are those - a growing number - who use the DCA (Dollar-Cost Averaging) strategy, or simply put, averaging. The idea is simple: you buy cryptocurrency for a fixed amount at regular intervals - for example, once a day or once a week. It doesn't matter whether the market is up or down - you keep buying. In the long run, this helps smooth out volatility and reduce risk. Why does it work? Because no one can predict the bottom with precision. But with DCA, you take emotions out of the equation and enter the market gradually, at average prices. This works especially well in a rising market - for instance, in Bitcoin's case, this st…  ( 12 min )

Hello fellow developers and tech enthusiasts! Welcome to a journey into the heart of containerization, where we explore the fascinating world of Docker. If you're building, deploying, or managing applications, you've probably heard of Docker – and for good reason! It’s a powerful tool that helps you package your software into standardized units called "containers." Think of it like this: your application and all its bits and pieces (libraries, settings, etc.) are neatly put into a shipping container. This container then runs smoothly and consistently, no matter where you move it – from your laptop to a big server in the cloud. This solves the classic "it works on my machine!" problem. Docker makes development easier, deployment faster, and scaling applications more efficient. But to truly …  ( 6 min )

Working with Java Spring Boot and Docker, I kept hitting this frustrating error during build: /bin/sh: ./gradlew: not found No matter what I tried, Docker just couldn’t run the Gradle wrapper inside the container. Turns out the culprit was something subtle — Windows CRLF line endings on gradlew. When you build a Docker image with a Java project using Gradle, the gradlew file must be copied into the container and be executable. But if you’re on Windows, gradlew often has CRLF (Carriage Return + Line Feed) endings instead of Unix’s LF endings. Linux-based containers can’t execute scripts with Windows line endings properly, so it throws a “not found” error. This problem is especially sneaky because your file looks fine on Windows and even inside Docker it shows up — but it silently fails when run. Check line endings in your editor (VSCode, Notepad++ show line endings). Run file gradlew on Linux — if it shows CRLF line endings, that’s the issue. Add RUN ls -la after COPY in Dockerfile to confirm gradlew is copied. Try running chmod +x ./gradlew — no errors but still ./gradlew: not found. Use tools like dos2unix gradlew locally before building. Configure your Git to checkout with LF line endings: git config --global core.autocrlf input Set your editor to save files with LF endings. RUN apk add --no-cache dos2unix \ && dos2unix ./gradlew \ && chmod +x ./gradlew COPY . . RUN apk add --no-cache dos2unix \ && dos2unix ./gradlew \ && chmod +x ./gradlew RUN ./gradlew bootJar --no-daemon -x test This tiny line endings mismatch wasted hours of debugging for me, but now you know the trick to avoid it. Make sure to: Check your line endings, Convert them properly, And always test inside your container early. This simple fix will save you headaches and speed up your Docker + Gradle builds!  ( 4 min )

A couple of months ago, I wrote a blog post on how you can create Model Context Protocol (MCP) servers using C#. Using a basic API, I was able to create a MCP server that allowed me to call Australian Football League (AFL) data and supply that as context to LLMs so I can ask it question about AFL results, teams, stats etc. using that API. That blog post talked about how we can use MCP servers that run locally on our machines using stdio transport. In this article, I'll talk about how we can use Server-Sent Events (SSE) transport to build remote MCP servers that we can host on Azure Container Apps. Model Context Protocol, or MCP for short, is an open protocol that standardizes how applications can provide context to LLMs. MCP provides a standardized way to connect AI models to different dat…  ( 9 min )

The convergence of Knowledge Graphs (KGs) and Large Language Models (LLMs) marks a pivotal moment in the evolution of the Semantic Web, promising a digital landscape that is not only more intelligent but also remarkably accurate and context-aware. This powerful synergy addresses inherent limitations of each technology when used in isolation, creating a more robust and reliable foundation for AI-driven applications. Large Language Models, while adept at generating coherent and grammatically correct text, often struggle with factual accuracy, a phenomenon commonly referred to as "hallucination." This limitation stems from their training on vast, unstructured datasets, which do not inherently provide a verifiable framework for facts. This is where Knowledge Graphs become indispensable.

SOME of you may know by now that I'm a fan of htmx and its hypermedia-driven website/application design philosophy. When people first learn about htmx, they are often captivated by the idea of hx-get, hx-post, hx-delete, etc. attributes being able to fire off HTTP requests with these methods from any tag on the page. I know I was! But it turns out there's a really good reason why we shouldn't just fire off requests with any method from any tag on the page: graceful degradation. The idea that even if the JavaScript on the page does not work for whatever reason–turned off on the user's browser, not loaded yet due to big scripts, or maybe due to a slow connection–the user should still be able to interact with most (if not all) of the functionality on the page. For example, if JavaScript does…  ( 7 min )

Hey everyone 👋 I’m planning to kick off an open source project inspired by platforms like ChatRoulette and Omegle.
